Among theobjects of the present invention is to provide a novel devicefor delivering at proper intervals measured quantities of fluid materialto successively presented lined containers, such as fiber cartons andthe like, 'and, at the proper.

,a greater number of filled cartons to an operator or operators whocomplete the folding and closing operations on the said containers toproduce the finished packaged goods.

- .A further object within the purview of the invention is to provide -anovel combination of means for feeding the containers into position forreceivin the fluid material andthe ejecting and closingmeans to,facilitate the packaging of the material whereby increased; productivecapacityis assured when compared with ordinary filling machine equipmentnow in use.

Still another object of the present invention is tQ provide a novelarrangement of the various control mechanisms for the fluid feeding andmeasuring means and the ejector and closing mechanisms which providesforpositive and controllable operation thereof under all circumstancesfor the proper delivery of the fluid material to the containers, theejection of the filled containers from their material receivingposition, and-the partial closing of the inner liner thereofwhenreceived in the immediate vicinity of the operator, thus facilitatingthe final closing operation and the, discharge thereof from the "machineby the operator.

.A furtherobject of the present invention-is to provide a novel combinedfluid" delivery mechanisnrand anti drip device, both of which arecontrolled by the. control mechanism for the proper sequential operationof. the anti-drip de-. vice toward the end of the delivery cycle toprevent dripping of the material over the con- .tainers as the same passunder the discharge nozzle or spout.

Still another object of the present invention is to provide a novelpower drive for the various mechanisms of the device readilycontrollable for intermittent operation thereof by the operator at themachine; the said intermittent movement of such control mechanisms beingeffected by way of a one-half revolution clutch of novel construct onwhich is positive in its action to control with a high degree ofexactitude the operation of these control mechanisms.

The invention still further includes as an object the provision of'anovel control mechanism for the ejector and folding mechanisms properlysynchronizedin respect to the operation of the other mechanisms of thedevice to successively eject the containers from the feeding line intothe environment of the operatorand to fold the panel of an innerlinerfor the container. The ejecting mechanism is of such form andconstruc tion as to provide positioning means for the containersdisposed upon the in-feed conveyor and is of'such construction as to bereplaceable by similar devices, varying in size, however, to accommodatecartons ofvarious sizes and shapes.

Referring now more in detail to the'drawings, adevice made in accordancewith the present invention and selected to illustrate the same is shownas'comprising aframe structure, generally referred to as 2, supportedupon the foundation or floor 4 and adap't'ed'to provide a mounting forthe various instrumentalities and mechanisms in proper relation to oneanother. Since this frame is of somewhat conventional constructionembodying such elements as the upright elements 8 and cross pieces 8.,as wellas variousbrackets and supports, such as It], further referenceto th detailed structure of this frame will not be made except insofaras is necessary in conjunction with the further detailed explanation ofthe various elements of themechanisms to behereafter more fullydescribed.

The device herein contemplated is of the automatic type embodyingcertain instrumentalities for successively and progressively filling andsaid containers.

positioned by a stop and ejector'mechanism. generally referred to as #8,which operates in in-feed conveyor, generally referred to as 52, which,as will be cxplained'hereinafter, is con-,

tinuously driven for successively moving opened cartons into a positionbeneath the discharge nozzle 14 of a metering and delivery mechanism,generally referred-to as 16, which successively delivers'measuredquantities of fiuid material to The containers are normally propersynchronized relation to the fluid delivering means for successivelydischarging the filled cartons onto a table or platform 2!! latterallydisposed with respect to the in-feed conveyor l2. Closely associatedWiththe stop'and ejector mechanism is a slider mechanism, generthemachine through the medium of a discharge conveyor generally referred toas 22;

In conjunction \vith'the various mechanisms above referred to in ageneral way is a control mechanism, generally referred to as 25, foroperating the various elements of the device in proper sequence andwhich is under control at an times of the, operator at the front of themachine i The various crated through the medium of a prime mover 28inthe form of an electricniotor mounted upon the platform 30- supported bythe frame 2 and which, through the driving pulley :32 and belts 33operates the pulley 34mou'nt'ed'on a shaft 36 'journaled in the spacedbearings, such as 38', secured tothe' frame 2, and upon which shaft 36is mounted a sprocket 49 which, chain 42, operates a sprocket 44 mountedupon one end of theshaft 46. "Shaft 46 isjournaled adjacent its ends inthe bearings 48 and 5!! secured to frame 2 and'disposed adjacent the topof the said frame structure 2. Mounted upon the shaft 46 are thesprocket wheels 54 and 56 which drive the conyeyorchains 58 and 60,respectively, which pass over the same and which serve as the in-feedconveyor for the cartonsto be filled by the machine. These chains 58'and 65 pass over sprocket pulleys, such-as62, disposed in opposedrelation to the sprocket pulleys 54 and 56 at the opposite end of themachine and' which are mounted upon a shaft 64 'journaled in fixedbearings 66 secured to' the frame structure 2 adjacent its-upper part todispose said chains at substantially'the level of the-table or platformfor moving the cartons successively and progressively into abutmentwiththestop and ejector ,mechanism wand beneath the spout H, as will beexplained'more ini detail as "the de scriptionproceeds. 'j

' The discharge conveyor generally referred to elements'of the'machineare 015-- through the as .22 comprises a belt pul1ey;68 mounted'uponshaft 46 and over the peripheryof which passes the belt which extendslongitudinally of the machine and passes over the belt pulley I2 mountedupon shaft I4 which is journaled in the bearings 16 secured to the framestructure .2 adjacent the: top thereof to dispose" the. said pulley I2in opposed relation to the pulley 68 As asomewhat conventional conveyorstructure, the guide elements 18 and 80 may be provided on oppositesides'of the in-feed conveyor, the-said guides I 8 having as asupplement thereto I an adjustable guide member 82 which may be movedlaterally with. respect to the conveyor chains 58 and 60. Furthermore,the discharge conveyor 22' may be formed with similarguide'members,

such as 84 and 86, on opposite sides of the belt I0 to properly guidethe filled cartons as the same are discharged from the machine- Thecontrol mechanism 26 is enclosed within a housing 88mounted upon theframe structure 2 by way of the channel members 90 and 92 and embodiesin part a shaft 94 mounted in the housing 96 through the medium of thespaced anti-friction bearings 98 'and100 and which said housing issecured in an opening in one of the front plates of the housing 86 bythe peripheral flange I02 and the stud bolts I04. This shaft extendsthrough the outer end of the housing 96 and has mounted thereon thesprocket wheel I06 which is continuously driven through the medium ofthe chain I08 which passes around and is driven-by the sprocket IIOmounted uponthe transverse power shaft 46. The housing 96 is madesubstantially'fluid-tight at its inner end by way of the cover plate II2secured thereto as by means of the stud bolts II4 to prevent loss oflubricant which is retained within the housing 68 for the variouscontrol elements to be hereinafter described. Adjacent the outer end ofthe shaft 94 is a gasket or washer I I6 of leather, or other flexiblematerial, to preventthe ingress of dirt and other foreign material intothe bearings' for said shaft.

The power drive half revolution clutch, generally designated as I I8,the details of which will be hereinafter more fully described, but whichincludes a clutch member I20 fixed to the inner end of shaft 94 and aclutch member I22 fixed tothe inner end of the shaft I24 in substantialalignment with and driven by the shaft 94 through the clutch H8. Theshaft I24 adjacent its inner end is mounted for rotation inanti-friction bearing I26 supported within bearinghub I28 of a partitionmember I30 extending transversely of the housing 88 and formed integralwith the opposed walls thereof. The shaft I24 has its outer endjournaled in the anti friction bearing I32 mounted in the bearing hubI34 of the rear partition wall I36, the said shaft being positioned bymeans or the adjusting locknut I38 threaded t0 the extreme end of saidshaft I2 4. The entire journal bearing at this end of the shaft issuitably enclosed by the closure cap I40 secured to the end wall I36 asby means of the stud bolts 142 orrthe like.

, Mounted upon the shaft I24 are the cammem bers I44, I46 and I48constituting control elements for certain of the mechanisms, and thestructure of which will be hereinafter morefully described; i

The control mechanism further embodies a shaft I50 extendingsubstantialyparallel to the through the shaft 94 for the controlmechanism is effected by way of a oneshafts 94 and I24 and which isrotatablylmounted through the medium of the spaced. bushings I52 and I54in the sleeve I56 journaledlthr'ough the medium of a bushing I58 in thebearing hub I60 formedin the front plate of the housing 88. The shaftI56 and sleeve I56 are protected against excessive wearby virtue of theretainers I62 and I54 suitably mounted, as shown inFigure 7, in thesleeve I56 and the bearing hub I60, respectively, to prevent the ingressof dirt or other foreign substances into the environment of said shaftand sleeve. The assembly atthe inner end of the sleeve I56 is positionedby means of. the collar I66 secured to the shaft I50 by .the pin I68.Shaft I50 transmits rotary movement thereof to a lever I10 connected tothe shaft at its outer end and which lever operates the valve of thematerial-feeding means, a will be'hereinafter more fully set forth.Keyedfto the rotatable sleeve I56 at its outer end is a lever I'I2pivotally secured at its opposite end to a connecting rod II4 whichin'turn is connected to the foot pedal as at I16 whereby controlmovements from the pedal are transmitted to saidrotating sleeve I56 tocause angular displacement of the clutch control element H8 which issecured asby means of welding I or the like to the inner end-of saidsleeve and which projects toward and serves as a means of con trollingthe clutch II8. :Theinner endof shaft I50 is journaleddn-a bushing I82,which in turn is mounted in' the bearing hub I84 provided in thepartition member I30. The bushing I82 is retained in operativ'e'position with the bearing hub [84 by means of the collar I86 secured tothe shaft by the pin I88. The shaft I50 extends through the bearing hubI84 and has mounted on its inner end the hub 190 of the cam follower armI92 which is provided at its other end with'the transverse stub shaftI94 upon which is. mounted acam roller I96 operating within a cam grooveI98 0f the cam I44, whereby movement of shaft I50 takes place in propercoordinated relation to other elements of the control-mechanism tooperate lever I10, all as will be hereinafter more fully disclosed.Washer 200 is provided between the hub I and thebearing hub I84toproperly adjustthe shaft I50 and to take up wear between hub I90 andthe bearing hub I814. q 1 The construction of theone-half" revolutionclutchis morereadily comprehended by reference to Figures"? and 9to15inc1usive. The clutch member I20 is formed on its face with aplurality of teeth 202 adapted to receive the teeth 204 movementwithinsuitable openings or recesses provided in clutch member I22 andisnormally urgedoutwardly with respect to said clutch member I22 throughthe medium of the coil springs 2| 2 whereby the said paWIS, under theimpulse of springs 2I2, will engage the teeth" 202 of clutch memberIZO.p i I Since the present invention contemplates the intermittentoperationofthe various mechanisms controlled by cams 'I44, I46 and I48,and thenonly under direct'control of the operator through the mediumof the pedalI16, novel means ispro "vided for normally holding the pawl clutch elements 208 and2I0 out of operative engagement with the teet of clutchmember. I20, I the said interlocking of the pawl clutch elements withthe teeth of clutch member I being effected only as desired and uponoperation of the foot pedal I18 by the operator. One of such controlelements has been referred to as I18, and since intermittent halfrevolutions of the shaft I24 are desired, as will later appear, a secondcontrol element 2I4 is provided in opposed relation to control element I18 and which is mounted by way of the bracket 2 I 6 to the housing 88.

The movement of the control element I18, as hereinbefore described,takes place upon angular movement of the sleeve I56. The pawl clutchelements are of similar construction, and while the control elements I18and 2 I 4 ar of somewhat similar construction, nevertheless there aresome differences as will appear as the description proceeds. The controlelement I18 is formed with a cut-out formed in part by the stop shoulder2I-8 and in part by the cam surface 220. When the control element I18 isin its normal position, the

same is in the way of the pawl clutch element 208 with its under curvedsurface corresponding essentially to the surface 222 of the controlelement 2 I4 bearing over the surface 224, and with its cam surface 220in engagement with the cam surface 226 of the pawl clutch element 288.Abutment stop 2I8 is in engagement with the stop shoulder 228 of thepawl clutch element 208 when the clutch is disengaged and controlelement I 18 is in its normal position. When these elements are incooperative relation, the cooperating cam surfaces 220 and 226 cause aninward movement of the pawl clutch element 208 against the compressionof spring 2I2 to maintain the tooth 204 out of engagement with the teeth202 of the clutch member I20.. The control element 2I4, while similar inconstruction to the control element I18, does not have a stop shouldercorresponding to stop 2I8 of control element I18. Thus, while the pawlclutch element 2I0 is moved by the control element 2I4 simultaneouslywith movement of pawl clutch element 208 by the control element I 18,there is no positive interlock between these elements and control of theclutch is through the control element I 18.

When it is desired to transmit motion to shaft I24, the clutch element I18 is moved through the operation of sleeve I56 to disengage stopshoulder 2I8 from the stop shoulder 228 and to disengage cam surface220from cam surface 226, thus permitting the pawl clutch element 208, underthe impulse of spring 2I2, to engage a tooth 282 of clutch member I20 tocouple shaft I24 with shaft 94. Simultaneously with the movement of pawlclutch element 208, pawl clutchelement 21l0-rides over the cam surface220 of the control element 2I4, and under the impulse of spring ZIZlikewise engages a tooth 202 of clutch member I20.

In order to assure proper and smooth operation of the clutch mechanism,thev opposed faces 222 of the said control elements I18 and 2I 4arecurved as disclosed and cooperates with the curved surfaces, such as 224and 230, of the pawl clutch elements .288 and 2I0. Y The cooperatingsurfaces 220 and 226 of the clutch controlelements and the pawl clutchelements are developed as screw surfaces to facilitate proper operationof the said pawl clutch elements into and out of engagement with theteeth of clutchmember I20.

The present clutch mechanismalso embodies a particular form of toothstructure-for both the clutchmember I20 and the pawl-clutch elements 208and 2I0, including the cooperative radial faces as at 232, whichassuresaipositive drive in both directions, thus-preventing over-riding of theclutch member I22 in respect to clutch member I20. Furthermore, theclutch control element 2 I4 is provided with stop 234 which, when incooperative relation with either of the pawl clutch elements 208 or 210,prevents reverse rotation of the clutch member I22 which might otherwisetake place in that the springs 2I2 have a tendency to cause this reverserotation by their application of an axial force to the pawl clutchelements. i f m In order to maintain clutch control element I18 incooperative association witheither of the pawl clutch e1ements'208 or210, the said clutch control element extends from the sleeve. I58through a U-shaped bracket 236 connected'to a wall of the housing 88,the said controlelement I 18 being urged forwardly intocooperativegrelation with either of the pawl clutch elements 208 or 2I0by a coil spring 238 embracing the positioning elements 240 and 242 atits opposed'ends which are connected to the control element I 18 and thewall 7 244 of housing 88, respectively, and abutting said controlelementI18 and wa11244. 7

Movement of'the foot pedal i16 through the medium of the connecting rodI14 and lever I12 v angular displacement of sleeve I55 which v istransmitted to the control element I18 which,

against the movement of coil spring238, becomes disengaged frorneither'of the clutch elements 208 or 2H]. Upon releaseof the foot pedalI16,

however, the control element I18 is returned under the impulse of spring238 intolposition to intercept either of the pawl clutch elements 203The metering and delivery mechanism I6 in- 1 cludes a double-actingmetering cylinder 246 mounted as indicatedupon the bracket I0 of theframe structureZand which has afreetfioating piston for measurin anddelivering through the pipe 848 quantities of fluid materialto thedischarge Ih'TZZIe I4, the device in the present instance being designedparticularly for delivering lard in fluid condition to the containers orcartons successively delivered into position beneath the end of theno'zzleor spout I4 for receiving charges of said lar d ,a1though it iscontemplated that the machine may be used for packaging other materialsif seennt to do so.

This fluid measuring device is controlled by a four-way valve 250,which'in turn is controlled through a uni ersal linkage'252 connected tothe valvestem 25! at one end by the operating lever 253 and to the endof thevalve lever I10, whereby the operation of the fluidmeasuringdevice is effected in proper sequence withthe other operatingmechanisms-of the device, itfbeing understood, of course, accordancewith the previous description, that thefoperation of lever I10 is inaccordance with the angular displacement of shaft I which takes place inaccordance with the movement of cam "I 44 operatingupon the cam rollerI915.

The spout or nozzle M, as previously alluded'to, has angulardisplacement as shown particularly in Figure 5 of the drawings, and inorder to accommodate such movement the said spout or nozzle, as moreparticularly shown in'Figure 4 of the drawings, is, provided with a hub254 embracing the and of the pipe 256; which is connected to the pipeconduit -248ethroughthe T-connection 258. Th s n -peq fi s mounted inthe bearing 260. secured tots top of theframe structure 2, and

not only positions the nozzle or spout, I 4, but

likewise the anti-drip mechanism 262 to be later described. Theend ofth-e pipe 2 56 i closed as at 264 and is provided with a threadedextension 266 adapted to extend through an end wall 268 of the nozzlehub 254 and through the medium of an interposed washer 210 and a locknut 212 is adapted to position said hub with respect to the pipe orconduit 256. Closure cap 214 threadedly engagin the hub 254 at one endis provided to enclose the end of this assembly to prevent leakage andto provide against the ingress of any dirt or foreign substancestherein. The opposite end of this assembly is likewise provided with aclosure; cap 216 threadedly engaging an opposed end of hub 254andembracing a gasket or washer 218 to-effect a tight'conneotion at thispoint.

The discharge conduit 256 about which the spout 288 is connected to theupper end of rod 288 extending downwardly through the housing 88 andjournaled at one end in the bearing gland 290. This connecting rod 288is secured'to the upper end of a saddle 292 straddling the shaft I24 andwhich is provided with a cross-head 284 provided -v with a cam roller286 operable within the cam groove 2880f the cam I46. This cam I46,through the medium of the cam roller 286 and saddle 292, causesreciprocation of the connecting rod 288 to impart angular movement tothe spout I4 in predetermined sequence in the fluid delivery cycle, thespout [4 being in its lowermost position when delivery of fluid materialtakes place, and the upward movement being effected after delivery ofthe material to provide clearance for movement of the filledoontainerinto ejecting position and movement of an empty container intofilling position.

Movement ofthe ejector and slider mechanisms is secured by a lever 308mounted on the upper end of shaft 362 extending downwardly impartreciprocating movement to the piston 322 when the same is operated. Thebell crank lever 328 is further provided with an upstanding leg 336 inthe way of anextension 338 for the lever 360, so that when the levermoves into its dotted line position as shown in Figure 2 of thedrawings; the bell crank lever-328 is given a quick move mentcounter-clockwise; as viewed in Figure 5 of the drawings, to move piston322 downwardly; thus creating.asuctiondrawing :fluid from the end of thenozzle back into the discharge system to minimize dripping at the endofthe filling cycle. This fluid material sucked back 'into the system byoperation of the piston 322 of course is put back into thelsystem at:the beginning oi the next filling cycle through the -action of thespring 324. H

The combined stop and ejector mechanism' I8 is in the form of a movablestop 34oihavingia leg 342 extending transversely of the conveyor i2 andanother leg 344 spacedlongitudinally with respect to the leg342andextending innormal relation to a longitudinally. disposed leg s 346;This movable stop member is adjustablysecured as by means of the wingnut and bolt assemblies, generally referred to as 348, to the"cross-head assembly 358 secured at the ends ofithe parallelly disposedrods 352 and 354 mounted for sliding movement in the fixed guides 356and 358. Immediately above, but independently of themov able stop 340 isa sliding blade 36ll'which, through the medium of the wing nut and boltassemblies 362, is adjustably secured to. the cross-head 354 mounted atthe end of the parallelly disposed rods 366 and 368, likewise slidablymounted in the fixed guides 356 and 358. i

This shaft 302 has a follower arm 352 connected adjacent its lowerend, which carries a shaft 3 l4 upon which is mounted a cam roller 316adapted to cooperate with a cam l groove 3i8 formed in the periphery ofthe cam 7 I48. Through the medium of the cam I48 the shaft 332 isrotated in predetermined sequence to and therefore in directcommunication. with the discharge conduits 248 and 258. This cylinder isprovided with a piston'322 spring-pressed upwardly by means of the coilspring 324 and the operation of which piston is effected by one leg 326of a bell crank lever 328 which is pivoted as at 336 to the closure orcontainer structure 88. The arm 326 has its free end extending through aslot 332 of the cylinder 320 and enages in the slot or recess 334 ofpiston 3 2 to of the, lever 318 which is 'pivotally connected as at 380to thecross-headw364; thisimovement of lever 318beingimpartedwbywaulinkx382 con nected intermediate .theends of lever318 and "having a pivotal;connectionwith the bracket 316. The other endof lever 316, as. at- 384, is

pivotally connected to a link 386 which in turn in pivoted as at 388 tothe bracket 396 extendindg laterally ofthe housing 88; p 1 l Referringmore specifically to Figures 16 inclusive, wherein certain of the partsimmedi ately hereinabove described are shown somewhat: diagrammatically,it will, be notedthat the stop member 340 has various operativepositions transversely of the in-feed oonveyor l2. As is wellunderstood, one form of container which may i formed with anupper openend, the side walls,

forming the liner extending above the upper open end of the carton 392,all as clearly shown;

in Figures 19 and 20 .of the drawings. These cartons with the linerdisposed therein are fed onto the conveyor I2 and are carried into: aposition such as shown in Figure 16 whereby the foremost carton isdisposed directly beneath the open end of the spout l4. When thisforemost;

carton is in. the position disclosed in Figure 16, the end of the spouthas been lowered into the interior of the liner to deposit a measuredquantity of the fluid in the carton. While the conveyor I2 iscontinuously operated, nevertheless the foremost carton is temporarilyarrested in its movement on the conveyor by the stop memher 349' which,when the foremost carton is moved into receiving position, has its legM2 disposed in respect to the conveyor 52, as shown in Figure 16, so asto act as a stop member for said foremost carton.

After a dispensing operation has taken place, the nozzle I4 is angularlydisplaced in accordance with the previous description, and the movementof the rods 352 and 354 is such as to retract the stop member 340 fromits engaging relation with the end of the carton being filled, all asdisclosed in Figure 17 of the drawings,

wherebythe foremost container which has then been filled with fluidmaterial is picked up by the conveyor I2 and moved into engagement withthe stop leg 344 of said stop member 340. Simultaneously with themovement of this foremost carton,.the next adjacent carton to the rearthereof moves into filling position directly beneath the discharge endof the spout I4, at which time the control mechanism is operated tolower the spout to discharge material into said carton. Simultaneouslywith the filling of the next succeeding carton, all in accordance withthe above disclosure, the rod 3'52 and 354 are moved through the mediumof lever 390' and link 3') to engage the first filled carton abovedoscribedi'to move the same laterally from the conveyor chains 58 and 60and onto the table or top 20, as shown in Figure 18 of the drawings.During this movement of stop member 340, the leg 342' thereof, whilemoving laterally with respect tothe next immediate carton being filled,nevertheless is of such a length that it still provides a; stop memberfor said carton.

During movement of the stop member 34'!) for ejecting the filledcartons, the sliding blade 3% is moved transversely of the conveyor I 2'through the medium of the rods 36S"and 368by way of' the linkagehereinabove described, into engaging relation with the front panel 398of the liner, all as disclosed in Figure 20 of the drawings, to foldsaid panel downwardly into substantially horizontal engaging relationwith the material contained within the carton, and simultaneouslyeffecting a fold of the end panels, such as 4%,

example, upon operation of the shaft I24, cam Hit causes rotation ofshaft I 50 through the medium of the cam rod' I92, which rotation ofshaft I50 causes movement of lever III]. This lever, through theuniversal linkage 252, operates the conventional four-way valve 250 tooperate the measuring device I6 to deliver through discharge pipe 2'48 ameasured quantity of fluid material through the discharge nozzle I4, ashereinbefore described. This same rotation of shaft 524 operates cam I45, which, through the medium of roller 296, causes reciprocation of rod288, which raises and lowers the spout I4. This same movement of shaftI24 further causes rotation of cam i it, which operates through roller3I6 to of the lever 3t!) which, while having the primary function ofoperating the stop and ejector mechahisrn, as well as the mechanism forpartially folding the liners, has, in addition, the secondary functionof moving the bell crank lever 328 to operate the anti-drip mechanism atthe end of a filling cycle;

As is apparent from the above description, the shaft i2 2 is stationaryin a definitely fixed position at the end of one-half revolution.Inasmuch 7' as the operator releases the pedal I'Ifiafter eachoperation, clutch'element I18 has been released, so that at the endof'the cycle of operation of shaft I24, the clutch H8 is automaticallydisengaged. Th shaft 84, how-ever, drivenrthrough the sprocket I96,continues to rotate during the operation of the machine. 7 It is to benoted that the cam I 38 which operates'the lever 380, and

livery of a full charge of fluid material'from the ,metering cylinder246 at each one-half cycle of the valve movement.

For each predetermined volume of fluid delivered by themetering cylinder258, however, the filling spout I4 and carton which facilitates furtherfolding of the liner and closing of the top flap 394 of the carton. Uponejection of the filled cartons onto the table 26; with the front panelof the liner folded as described, the operator standing in front oftable 7 20' can then complete the folding of the liner and the closingof the flap of the cartons as the same are successively ejected from thein-feed conveyor, after which the same may be placed in contact with thebelt I'll of the take-away conveyor for discharge of the same from themachine.

As hereinbefore alluded to, the operation of the device in accordancewith the immediately above description takes place intermittently whenthe operator presses upon the pedal I16. This initiates operation of theone-half revolution clutch II8, causing a one-half revolution of shaftI24,

which operation affects th other control elements to bring about certainoperations of the various instrumentalities in proper sequence toproduce the results hereinbefore described. For

through a full cycle. i
